Sunroom Conversions & Upgrades
Transform your existing sunroom into the comfortable, modern space you have always wanted.

Your sunroom has good bones, but it is not working the way you need it to. Maybe it gets too hot in summer or too cold in winter. Maybe the old windows leak or the finish looks dated. Instead of tearing everything down and starting over, you can often upgrade your existing sunroom to solve problems and improve comfort at a fraction of the cost of new construction.
Common Sunroom Conversions We Handle
Every conversion project is unique, but we see certain types of upgrades regularly. Here are the most common ways Hesperia homeowners improve their existing sunrooms.
Three-Season to Four-Season Conversion
This is one of our most popular upgrades. Your three-season sunroom works great part of the year but sits empty when temperatures get extreme. We can add insulation to the walls and roof, upgrade to energy-efficient windows, and extend your HVAC system into the space. The result is a four-season sunroom you can use comfortably year-round.
Screen Room to Glass Enclosure
If you currently have a screen room but want more protection from weather and dust, we can replace the screening with windows. This transforms your screen room into a three-season or even four-season sunroom depending on how much insulation and climate control we add.
Window and Door Replacement
Old windows can leak air and water, reducing comfort and causing damage. Upgrading to new energy-efficient windows improves temperature control, reduces drafts, and gives your sunroom a fresh look. We can also replace old sunroom doors with modern units that operate smoothly and seal properly.
Performance Upgrades to Consider
Beyond major conversions, there are several upgrades that can dramatically improve how your sunroom functions.
- •Insulated Glass: Replace single-pane glass with insulated units to reduce heat transfer and improve comfort
- •Roof Insulation: Add proper insulation to the ceiling to prevent heat buildup in summer and heat loss in winter
- •Climate Control: Extend your HVAC system or add mini-split units for heating and cooling
- •Ceiling Fans: Improve air circulation and comfort without the cost of full climate control
- •Electrical Upgrades: Add outlets, lighting, or circuits to support your needs
- •Flooring: Replace worn or damaged flooring with tile, vinyl, or other durable materials
How We Approach Conversions and Upgrades
Every conversion project starts with a thorough evaluation of your existing sunroom. We look at the structure, foundation, frame, and current condition. This helps us determine what upgrades are possible and what they will cost.
Not every sunroom is a good candidate for conversion. Sometimes the existing structure has limitations that make starting fresh a better choice. But in most cases, we can work with what you have and deliver significant improvements at reasonable cost.
We discuss your goals and budget, then recommend the upgrades that will give you the best return on investment. You might discover that a few targeted improvements solve most of your problems without needing a complete overhaul.
What to Expect for Cost and Timeline
Conversion and upgrade costs vary widely based on what work you need done. Simple upgrades like replacing windows or adding ceiling fans cost much less than a full three-season to four-season conversion. Generally, upgrades cost 40 to 70 percent of what new construction would run, making them an attractive option when your existing structure is sound.
Timeline depends on the scope of work. Minor upgrades might take just a few days. Major conversions that involve insulation, new windows, and HVAC work can take two to three weeks. We provide clear schedules and keep you informed throughout the project.
One advantage of conversion work is that you often have less mess and disruption than building new. We are working with an existing structure, which means less demolition and foundation work. Many customers continue using the rest of their home normally while we complete the sunroom upgrades.
